A painful attack delivered to a woman's vulva, such as a kick, knee, stomp, punch etc. Made to punish, for fun or to keep them aware of that they are not superior over men regarding genital attacks. The attack is deadly effective in incapacitating the woman since this is agonizingly painful.

When she tried to kick me, I got a hold of her leg and made a cuntbust so hard that left my shoe impression.

When the man cuntbusted her, she fell down grabbing her fanny and started coughing.

After a hard cuntbust, she was rolling on the ground and asking for water.

She never tried to kick any man after she was rendered barren with a devastating cuntbust.
